Papillary endothelial hyperplasia —a case report of this rare vascular lesion

We will report a case of intravascular papillary endothelial hyperplasia, an unusual blood vessel disease occurring in the oral cavity. A female patient, 54 years of age, showed a bluish asymptomatic nodule in the lower lip, measuring 5 mm in diameter. The clinical diagnostic hypotheses were hemangioma or mucocele. An excisional biopsy was performed. The histopathologic examination demonstrated papillary tufts with a central hyaline core lined by a single layer of endothelial cells, which were positive for CD31 staining.
